What Is The Correct Order Of The Parts Of The Respiratory System? - Fixanswer

The respiratory system includes

the nose, mouth, throat, voice box, windpipe, and lungs

. Air enters the respiratory system through the nose or the mouth. If it goes in the nostrils (also called nares), the air is warmed and humidified.

What is the correct order of the respiratory system?

The flow of air from the environment moves through the respiratory system in these sequential steps during inspiration:

Nose or mouth > pharynx > larynx > trachea > the right or left bronchi of the lung > bronchioles of the lungs > alveoli of the lungs

.

What are the parts of the respiratory system and their functions?

Pharynx (throat): Tube that delivers air from your mouth and nose to the

trachea

(windpipe). Trachea: Passage connecting your throat and lungs. Bronchial tubes: Tubes at the bottom of your windpipe that connect into each lung. Lungs: Two organs that remove oxygen from the air and pass it into your blood.

What are the 10 parts of the respiratory system?

Nose.
Mouth.
Throat (pharynx)
Voice box (larynx)
Windpipe (trachea)
Large airways (bronchi)
Small airways (bronchioles)
Lungs.

How does air move through the respiratory system?

When you inhale through your nose or mouth, air

travels down the pharynx (back of the throat)

, passes through your larynx (voice box) and into your trachea (windpipe). Your trachea is divided into 2 air passages called bronchial tubes. One bronchial tube leads to the left lung, the other to the right lung.

What is the pathway taken by air in the respiratory system?

Respiratory System:

Pathway of air: nasal cavities (or oral cavity) >

pharynx > trachea

> primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles > alveoli (site of gas exchange)

What is the most important part in the respiratory system?

The Lungs

. The lungs are paired, cone-shaped organs which take up most of the space in our chests, along with the heart. Their role is to take oxygen into the body, which we need for our cells to live and function properly, and to help us get rid of carbon dioxide, which is a waste product.

What is the structure and function of the lungs?

The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). The trachea (windpipe)

conducts inhaled air into the

lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic.

What is the main function of the respiratory system?

Your lungs are part of the respiratory system, a group of organs and tissues that work together to help you breathe. The respiratory system's main job is

to move fresh air into your body while removing waste gases

.

Do lungs help blood get around your body?

Blood with fresh oxygen is carried from your lungs to the left side of your heart, which pumps blood around your body through the

arteries

. Blood without oxygen returns through the veins, to the right side of your heart.

How many parts are in the respiratory system?

There are

3

major parts of the respiratory system: the airway, the lungs, and the muscles of respiration. The airway, which includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles, carries air between the lungs and the body's exterior.

Which muscles do we use to breathe?

Your main breathing muscle is

the diaphragm

. This divides your chest from your abdomen. Your diaphragm contracts when you breathe in, pulling the lungs down, stretching and expanding them. It then relaxes back into a dome position when you breathe out, reducing the amount of air in your lungs.

What is the pathway taken by air in the respiratory system illustrate with a Labelled diagram?

Air

enters the nostrils passes through the nasopharynx

, the oral pharynx through the glottis into the trachea into the right and left bronchi, which branches and rebranches into bronchioles, each of which terminates in a cluster of alveoli Only in the alveoli does actual gas exchange takes place.

What important activity takes place in the lungs?

The main function of the lungs is the

process of gas exchange called respiration (or breathing)

. In respiration, oxygen from incoming air enters the blood, and carbon dioxide, a waste gas from the metabolism, leaves the blood.

What keeps food out of the lungs?

When you breathe, air enters your mouth and moves into the pharynx. The air then goes down into your main airway (trachea) and into your lungs.

A flap of tissue called the epiglottis

sits over the top of the trachea. This flap blocks food and drink from going down into the trachea when you swallow.
